Answer:
There are 6 coins in nickels and 9 coins in quarters.
Step-by-step explanation:
Now, to find the solution.
According to question:
The number of nickels = 
.
The number of quarters = 
So, the total number of coins:
He had 3 more quarters than nickels.
Thus,
.....(1)
Now, to get the solution:
Substituting the equation (1):
<em>Subtracting both sides by 3 we get:</em>
<em />
<em />
<em>Dividing both sides by 2 we get:</em>
<em>The number of nickels = 6.</em>
Now, substituting the value of in equation (1):
<em>The number of quarters = 9.</em>
Thus, there are 6 coins in nickels and 9 coins in quarters.

Step-by-step explanation:
I haven't worked out the answer myself but here are the steps to follow for you to find out the answer.
First step is to find the angle of 'A'. Do this by using the <em>cosine rule</em> on the smaller triangle.
Formula for this is;
cos(A) = <u>b2 + c2 – a2</u>
2bc
Second Step is to find the length between AC. Do this by using the <em>Sine Rule</em> on the large triangle as a whole.
Formula for this is;
<u> a </u> = <u> b </u> = <u> c </u>
Sin(A) Sin(B) Sin(C)
Label the large triangle as CA=b and CB=a
This is so you have the length and angles of all parts but the one section in which you're trying to find, this should be the basis of your sine formula but fill in the angle of 'A' which you found before.
<u> 65m </u> = <u> b </u>
Sin(A) Sin(68°)
now get 'b' by itself
<u> 65m (Sin(68°))</u> = b
Sin(A)
Third step. Now that you have the length of b or AC, minus the length 27m to find the length of CD.
Hope this helps :)
For ax^2+bx+c
when a=1
take 1/2 of b and square it
that is what c should be ideally
p^2-30p=c
-30/2=-15
(-15)^2=225
c=225
(p-15)^2 is factored form
k^2-5k+c
-5/2
(-5/2)^2=25/4
c=25/4
factored form is (x-5/2)^2
